Save XY Coordinates

[OliverB]

Dear All

I am having issues with obtaining accurate measures pixel intensity  
with the "Save XY Coordinates" function. Specifically, the output (txt  
file) of this function never corresponds to actual pixel intensity  
values that I obtain when using the pointer tool for a give pixel.  
Usually the pixel intensity measured via the "Save XY Coordinate"  
output is a lot lower than the value listed by the pointer function. I  
have tried many different formats, but have never gotten a match  
between live values (i.e. with the pointer) and the XY coordinate  
measure.

Any insights?

Many thanks.

Interesting!

"Save XY Coordinates", as the name suggests, saves coordinates but no
pixel values, at least it does so for me.

If you use the point selection tool, you may use Analyze>Measure,
which reports point coordinates and pixel values. As far as I can see
it does so correctly.
